The full nature of said invention will be shown, and has secured thereon a mutilated at rest. In this way the cylinders as a plural ity or unit are given a suflicient rotationto turn the front longitudinal row of pictorial faces 310 up out of the way and bring into view another row of faces 310, which are in View during the remaining five-siXths of'the slow rotation of the shaft 15, and then another row of faces 310 are moved into view.

7 It must be understood that the driving shaft 15 operates comparatively slowly so as to lea've the row of pictorial faces 310 in view asufiicient length of time for the same to be satisfactorily viewed.

The foregoing gearing would intermittently operate all the cylinders simultaneously and to the same extent, but in order to vary the panoramic series of pictures it is desired to hold some of the cylinders so as tomake a new combination of pictures in the panorama or give longer view of some pictures as desired. l The means for accomplishing said result will nowbe explained.

Below the cylinders 10 and shaft 11 there is aecam shaft 13 on which there is secured a cam 20 under each cylinder. The purpose of each of these cams is to lift the holding plunger'2l from its disengaging position, as shown in Fig. 4, into a position to engage one of the corner frames 210 of one ofthe cylinders 10, as shown in Fig. 1, and thus stop it and hold it temporarily. This stop means is provided for each cylinder and is controlled ythe gearing and cams. The cam shaft 13 is driven by the shaft 15 through the train of gears 35, 36, 37 and 38. The gears 36 and 37 are mounted on a jack shaft journaled' in t the frame bars 12.

Each holding plunger 21 is vertically movable in its stationary guide plate 22.. Its

downward movement is limited by the collar 23 engaging said bar '22, as seen in Fig. 41. Its upward movement is caused by the cam20 on the periphery of which it rests or rides. The holding plunger 21 is held'down in the position shown in Fig. 4: by a spring 24 coiled around said plunger and at one end bearing against the stationary plate 22 and at the other end against a pin 25 in said plunger 21. The upper end 221 of the holding plunger is forked, as shown in Fig. 4, so as to not only engage the frame bar 210 but hold the cylinder from rotation when it is up in the position shown in Fig. 1.

Each cam wheel 20 has a series 'of recesses 26 in'its periphery, one for each side of its respective cylinder. Therefore, there are six of said recesses equidistant in the rim of the cam wheel.- The following edge of each recess 26 is curved from the'bottom thereof outwardly to the outer periphery of the cam Wheel, and the following edge is inclined; and the recess is wide enough toallow the heel 120 of the holding plunger 21 to enter a to cause theheel ofthe'holdi'ng plunger 21 to ride up out of the recess onto the periphery of the cam wheel, the forked end of the holding plunger 21 will be brought into holding engagement with its respective cylinder,

as'shown in Fig. 1, and that "willhold the cylinder from rotation until further rotation of the camwheel-in the direction "of the arrow in Fig. 2 enables the heel-121 of the hold ing plunger 21 to drop down into the followingrecessand release the forked end 221 from the cylinder, as seen in Fig; 4:.

The'recess'es 26 and the function of same are obviated Icy-segmental cam plates'27 pivoted at 28-to a side 'ofthe cam wheel 20in position so theouter or arcuate portion of the plate may register with the periphery of the wheel, as shown at a in Fig. 4 and as illustrated in Fig.5, and said -plate is yieldingly locked insuch position by [the spring '29 acting against a rounded head 30 that forces it into a notch 31 inthe side ofthe ca'm whe'el20, as 'seen'in Fig. '5. This will hold the plate 27 in its adjusted closed position until'it is'manually changed and moved out of the way, as is also true of the five plates 27 shown in Fig.4.

If allthe' plates 27 are moved so their cam surfaces'are aligned with the'periphery of thecam wheel 20' the heels 121 of the plungers will-beheld out of the recesses 26 when. the wheel is revolved by means of the toe 321' ridingon the cam surface ofthe plates 27, thereby causin'gthe forked end of the plunger to engage its 1 respective cylinder and keep it fromrotating, as seen inFig. 1, untilthe plates 27 are again adjusted's'o the heels 121 can again enter the recesses. It is obvious that one or more of the plates 27 can be adjusted to stop the rotation of their respective cylinder for a predetermined period during the rotation of the cam wheel.

Thus in the machine shown herein the timing might be as foll0ws: Thecylin'ders 10 could be revolved by the shaft 15 and mutilated gear 5 16 for one-sixth of a revolution, or 60, and for two'secondswh-ile the teeth in gear 16 mesh with the teeth in. gear 17. That would move the visible pictorial illustrations 4 row into view and they would remain in view for five-siXths of a revolution of the shaft 15, gear 16 and cylinders, or for ten seconds. Then the cylinders would be given a one-sixth revolution for two seconds, and this process would be repeated. However, by changing the gearing on the multilated gears, the timing of the cylinders could be correspondingly changed. The timing above described would give individuals ten seconds to View the pictures that the machinery in two seconds had brought into view, and, as stated, that time could be altered.

Likewise the gearing operating the cam wheels 20 would give to said cam wheels the movement corresponding to that given to the cylinders. Thus the gears 37 would be operated the same as gear 16 and turn the gear 38 and cam shaft 13 one-sixth of a revolution, say, for two seconds, and then the cams and cam shaft would be idle for llVQ-SlXiZllS of a revolution or ten seconds.

By relatively changing the different cam wheels 20 through the instrumentality of their cam plates 27, the cam wheels could cause the cylinders to be held or released from rotation according to any desired sequence. A single wheel 20, if the cam plates were adjusted as shown in Fig. l, would release its corresponding cylinder at the end of every movement of the cam, except during one segmental movement thereof its cylinder would be held at rest for almost 120. If all of the plates 27 were turned so as to close the notches in the cam plate, it would hold the cylinder locked at rest until the cam plates were readjusted.

Hence, there is a wide range of adjustment of the cams and holding means. lVhile the holding plunger 21 is forked at its upper end, that is not necessary as only one side of the fork functions by resisting the tendency of the cylinder to rotate. In the form shown in Fig. 4, it is the left hand branch of the fork l that holds the cylinder from rotation, but

the fork has its advantage by way of centering the cylinder.
